Old, is that thing a real old one, like a dash 3,5,or newer like a 6, or a real new one like a dash 7,8? Just by guessing from what you say, I'm thinking it may be a dash 3 or 5. Both are blue and yellow, on a dash 5 the side panels are flat, on a dash 3 there is a step on the side panels along the side where the blue and yellow meet. A dash 6 is more rounded at the counterweight and is yellow and grey. I believe the starting system on the dash 3,5,6 is all pretty close. Maybe NCWayne will know better on this, but I was thinking that the engine would still start with the safety lever up, that it just disabled the hydraulics? NCWayne probably DOES know better than me since I believe the dash 3,5 Komatsus were probably done being built before I was born lol. I did a rewire on a PC300-3 for a guy this summer, it has a wiring fire. The swing brake controller had shorted to ground and vaporized a lot of the harness, including the starting and alter alternator portion. After rewiring the melted wires and replacing the swing brake controller ($350), I now had a "no start" condition. I checked the alternator "R" terminal not running and had voltage. Needs an alternator. Replaced alternator. Tried again, no start, found that the battery powered battery disconnect was losing hold, burned up, and so was the starter solenoid. I replaced both of them and then we were cooking with gas. I am guessing the internals of the alternator, the starter solenoid, and the disconnect were ruined when the wiring shorted and all melted. After all of that, the only thing that didn't get ruined was the small relay or solenoid above the starter, I believe it is called a "safety start relay" but I can't remember for sure. If it is a dash 7, or 8, all I can say is "have a good time with that" lol.
